I have no idea but i think because long term activation is long term rather than nuclear. this is wrong
Answer:
the pH
Explanation:
The condition that should not be kept the same in each of the five test tubes is the pH.
Since <u>the aim of the experiment is to investigate the effect of pH on the activity of the lipase enzyme</u>, the pH is, therefore, the <em>independent variable</em>. Thus, it must be controlled or varied in all the test tubes in order to see its effect on the activity of the enzyme, which, in this case, would be the dependent variable.
Answer:
e. unique three-dimensional shape of the fully folded polypeptide.
Explanation:
The tertiary structure of a protein is the unique three-dimensional structure which emanates from the interaction between the “R groups” of the several amino acids that make up the polypeptide. Hydrogen bonding is one of the interactions that occur that gives the protein this structure. Other interactions are ionic bonding, dipole-dipole interactions, hydrophobic interactions, among others. The function of a protein is dependent on its tertiary structure, as a disruption of the tertiary structure causes a protein to be denatured, thereby rendering the protein not functional.
The right answer is 5.
To answer this question it is sufficient to take the same approach as the one that concluded that each amino acid is equivalent to 3 codons.
We have 17 amino acids, each of which must have at least one unique code (having two nucleotides A and T)
.
it is enough to apply this time to count the number of possible codons to be generated according to the number of nucleotides:
nucleotide set ^ number of nucleotides = number of codons
.
2 ^ 1 = 2 (<17)
2 ^ 2 = 4 (<17)
2 ^ 3 = 8 (<17)
2 ^ 4 = 16 (<17)
2 ^ 5 = 32 (> 17)
So, each amino acid has a codon of 5 nucleotides.
